Please Note:

WPA and WPA2 are both good encryption methods to secure your wireless network, and are more secure than WEP. However systems older than Windows XP Service Pack 2 do not support WPA encryption. If you have a wireless computer that pre-dates Windows XP Service Pack 2, you will have to use WEP as a security protocol in order to ensure connectivity of older machines.

Also, if WPA2 is available to you, it would be better to choose this option over standard WPA since it will allow wireless N devices to operate at their full capacity and network speeds if you have a wireless N router and wireless N network cards in the computers you are connecting.


  • First, open Internet Explorer or your preferred Internet browser.
  • Next, you will need to log in to the router. To do this, go to the address bar at the top of the page (the long white bar across the top of the screen which will contain the web address of whatever your home page is) and empty it by backspacing all text out of it.
  • Enter the router's IP address, which is by default set to Then press enter.
  • If everything is otherwise set up correctly, the browser should prompt you for a user name and a password. By default, for Linksys routers, the user name is to be left blank (do not type anything in) and the password is admin. Once you have that entered, press Enter on your keyboard, or click the OK button.
  • If the user name and password are accepted, the browser will load a Linksys Basic Settings page. If the user name and password are not accepted, the user name and password have been changed. If you do not know this information, you will have to reset the router.
  • Click the Wireless tab at the top of the Linksys Basic Settings page.
  • First, make sure that if you have an option for Manual security or Wi-Fi Protected Setup, that it is set to Manual. If it is not, set it to manual, then click Save Settings. Otherwise, continue on.
  • Directly under where you clicked Wireless, you will see a link for Wireless Security. Click this link.
  • This page will show you the security types available on the router. By default, the router will probably be set to Disabled.
  • To configure WPA or WPA2, select WPA-Personal or WPA2-Personal from the list of security options.
  • You will be prompted for a passphrase. This is the password that you want to set on the router. This can contain any combination of characters including letters, numbers, symbols, and spaces. The passphrase however must be at least eight characters long, and no more than sixty-four characters.
  • Once you have entered the passphrase you want, click Save Settings. The router will then reboot. If you are on a laptop, you will need to reconnect to the wireless network during which you will be prompted for the key that was just set up. If the computer is a Windows 7 or Windows Vista based computer, you will have to remove the old network profile before attempting to reconnect to the router, or you will get an error saying The profile saved on this computer does not match the requirements of the network.
  • WPA or WPA2 Security should now be enabled on the router. You will need to enter this key into each wireless computer you add to the network. Wired systems do not require a network key to connect.
